I haven’t done much with my 2.8 duramax yet, but I have experience with the full size duramax. And when tuning those you needed a lift pump. The lift pump was there to keep the fuel rails from being drained/loosing pressure, but also do a lot of other things for the bigger duramax’s. Such as reduce/eliminate air emulsification in the fuel, add better fuel filtration and water separation. Has anyone considered running a lift pump such as a fast or airdog on these little duramax’s ? I know on the 6.6 it greatly extends (basically prevents failure) injector life.
